' Application filed December 29, 1905. Serial No. 293,845. I

To all whom it may concern:

Be it known that I, Jnssn G. VINCENT, a

citizen of the United States, residin at De-- .troit, in the county ofIV-aync and State of dividual items and to print the total thereof atthe willof the operator and the object of my invention is to providesuch machine with means for registering or keeping count of the numberof checks or items put.

through the ,machine corresponding to the number of times that themachine is operated for the individual items and to record or print thetotal of the number of such checks or items at the will of the operator.In the present instance and by preference the arrangement is such thatthe total accumulated by such registering means or counter isautomatically printed by the act of taki-ng'a regular total (sub-totalor grand total) on the machine proper so that the number of checks oritems,cpmprised in such and at one side of such regular total. Todistinguish the two different characters of totals, that is theregulartotal and the item total. suitable means may be employed, as forinstance the/printing mechanisms concerned in the printing of suchtotals may be provided with a polychrome ribbon, wherebv the ,totals areprinted in contrasting My invention has application to that class ofmachines exemplified by the well known Burroughs adding machine made insubstan- 4.0

tial accordance With Burro-ughss Patents Nos. 504,963 and 505.078,issued on September 1 2.1893. but it will be understood that myinvention is not limited in its application or scope to machines of thistype or make, but that it may be employed in other machines used for thesame general purposes. Moreillustration of my invention, 1, have chosento show the same applied to a Burroughs 'machine and will hereinafterdescribe the some in that connection without intention of limitingmyself thereto.

. In the drawings Figure 1 is. a eft h n simultaneously with descriptionand.

side elevation of a Burroughs machine but I omitting parts which areunnecessary for an understanding of my invention; Fig. 2 a detail viewof a portion of the printing mechanism; Fig. 3 a plan view of theprinting mechanism, but illustrating the hammers in section; Fig. 4 asectional plan View (on line H of Fig. 1) of a portion of the forwardend of the machine illustrating the improvements or attachments; andFig. 5 a view in perspective of one of the operating connections formingone of the parts of my attachment.

As hereinbefore stated, I have shown my invention as applied to a.Burroughs adding machine and in addition I have chosen to utilizecertainportions of the accumulating mechanism and printing mechanism ofsuch machine to serve as special accumulating and rinting'mechanism forthe check or item counter and printer, although, as will be hereinafterunderstood, such special mechanism may be provided as an addition to aregular Burroughs machine. In the present instance I provide suchspecial mechanism by utilizing the accumulating and printing mechanismsbelon first two rows of keys on the le t hand side otthe keyboard and soadapt them and'put them under 7 the control of the machine proper thatthey will accumulate 1 for each, item put into the machine and, in thecomplete embodiment of my machine, I provide for automatically taking atotal of this special accumulation in the act of taking the regulartotal. The employment of the accumulating and printing mechanismscorresponding to two denominations will afford a capacity of 99 but aswill be obvious,- the capacity may be increased by in- "creasing thenumber of trains of such s eci a1 mechanisms. The machine, thus moified, is adapted to accumulate the items in the regular way and also tokee a special accumulation of the number 0 machine is operated with anitem set up on the keyboard, which will correspond to the machine is somodified and arranged that the printing mechanism now servlng as a.special printing mechanism will be rendered inoperative, so as not toprint 1 with each action of some of the parts constituting my ing to theV times that the number of items or checks. Moreover, the

t1on (in the special accumulating.mechanism special. printingmechanisms, the two differ- Erachcorresponding to that series. For initem, but will accumulate 1 every time that an item is put through themachine, but such special printing mechanism will be rendered operativewhenever the totalizing mechanism of the regular machine is set oroperated, with the result that the accumulawill be printed automaticallyand at one sideot the total or sub-total printed by the regular printingmechanism of the machine. Furthermore, by employing a polychrome ribbonor two separate ribbons of contrasting colors for serving the regularand the cut totals may be printed in contrasting colors so that they maybe readily distinguished one from the other. The Burroughs addingmachine being so well known and being described in detail in said priorBurroughs patents, only those parts thereof more or less concerned inthe operation of my improvements need be described. As usual, thekeyboard of the machine is provided with a series of keys 291 arrangedin rows corresponding to the different denominations increasing fromright to left, the keys in each row representing the digits 1 to 9.These keys are arranged to be set or de- Dressed according to the itemto be accumulated and as a result of the depression of a key in any oneof the rows, a sliding baror plate 214, one for each row of keys, ismoved rearwardly and at the same time a universal rod 4024; extendingtransversely of the machine is correspondingly moved r'earwardy wheneverany one of the series of sliding bars 214 is so moved, by reason of thecontact of a depending lug 214 on the operated sliding bar or bars. Asis well known, this; universal rod forms part of'a bail having parallelside arms 424. th left hand one f which'is illustrated in Fig. 1 Thus,the universal rod is moved rearWardl-v each time an item is set up onthe keyboard. v The adding machine is provided with a series of mainlevers orsectors 611- which are hung or mounted to oscillate on the maincross shaft 600. These sectors carry at their rearward ends the seriesof movable type plates 618-and at their forward ends carry the racks610. The degree of descent of thetorward end of one sector 611 and itsrack 610 is dependent u on the particular key operated or depresse inits correspond-' ing rowpf keys and this result is accomplished by meansof the movement of the stop wire 270, corresponding to theparticular"key so operate As is well known, each stop wire is movable asto itsforward and hent end 'initsproper slot formed in plates 210. V7hen a key is operated the foror bent end oi its stop wire is drawnrearwardly and into the path of movement of the projection or shoulderof the rack will be unlocked and be free to de-' scend a distancec'orres onding to the value of the particular key epressed, as alreadydescribed.

The racks 610 cooperate with a corre sponding series of accumulatingpinions 916, which are mounted to rock forwardly and rearwardly in aframe having end plates 910 mounted on an axis 900. The rocking of thisframe during the operation of the machine is controlled by a pitman 914,with the result that in the accumulating operation the frame is rockedforwardly out of mesh with the racks which are then permitted to freelydescend provided that any key in their corresponding row of keys hasbeen operated and such frame is rocked rearwardly into mesh with theracks just prior to the ascent of the latteron the rearward or returnstroke of the operating handle-or main shaft of the machine, so thatuponsuch ascent of the operated racks, the amount or value of the item istransferred to the accumulating pinions. This pitman, which thuscontrols the rocking or swinging of the pinion frame, is operated indirectly from the rock shaft 800 through the medium of the rock arm813, wipe plate 821 and the three-armed lever 91-3, having the two studs961 and 961*,with which the wipe plate directly cooperates.

In the tak'ng of a total the pitman- 914' is so controlled at the willof the operator that the rocking frame 910 .is prevented from beingrocked to carry the pinions out oi i'nesh with their racks, with v theresult that the racks are permitted to descend distances correspondingto the accumulation on the pinions and the printing mechanism thereuponprints the accumulation. If the total is to be a grand total, thetotalizing mechanism is left-in set or operated position,-wherenpon, onthe return stroke of the operating handle or main shaft of the ma chinethe. pinion frame is rocked to carry the pinions out of mesh with theracks and thus left at zero, but if the total is .to be a subtotal, thetotalizing mechanism released at the end of the forward operatingstrokeof the handle and the pinions there y left in mesh w ith the rackswhich will i v re-transfer the accumulation to the in maphinehereinshown, the

in the totaling opera- .ward end of the pitman may be lowered by theoperationof depressing the total key.

The printing mechanism comprises a series of hammers 715, one for eachsector 611 and adapted-to strike the forward end of any one of the typeplates presented to it and thereby make an impression upon the papercarried by the platen 1599. Each hammer has its separate driver 716, bywhich it is operated or driven, but each hammer is normally restrainedby its latch 717 which is mounted to oscillate so as to release thedriver and thereby operate the hammer. Each latch is under the controlof a pawl 718 which,'when its corresponding sector 611 is operated, isadapted to engage and rock its latch 717 and thereby operate its hammer.The series of pawls 718 are arranged in a rocking frame and engage theirlatches 717 only when their corresponding sectors have been operated,but those pawls 718 corresponding to sectors which have not beenoperated are rendered inoperative as to the tripping of their latches717 by being rocked upwardly by contact of 'heir tails with the inclinedshoulder 611 of their sectors s0 as to clear a shoulder on the upperedge of theirlatches. The latches are as usual formed with overlappingtails so that all latches to the right of the one associated with thebank of keys in which one has'been depressed for the hi hest decimalplace in an amount to be printed, will be tripped whether or not a keyis de ressedin a right-hand bank for a lower ecimal place. Thisautomatic tripping of latches is provided for-in order to have ciphersprinted in all decimal places to the right of the highest one whereverthe amount calls for no digits.

As hereinbefore stated, I modify and adapt the accumulating mechanismand printing mechanism corresponding to the first two denominations onthe left hand side of the keyboard for the purposes of my invention,whereby the number of items put through the -machine may be accumulatedand the total thereof printed at the same time that the regular total onthe machine is printed. According to the present described construction,that is one in which the accumulating and printing mechanisms of thefirst two denominations counting from the left of'the keyboard areemployed,

I obtain a 99 capacity but it will be understood that the capacity may.be increased either by including more of the regular mechanismscorresponding to the denominations to the right or similar trains ofsuch mechanism" maybe provided on the left of the regular machine. Or,as hereinbefore suggested, special accumulating and stop wirescorresponding its forward end laterally and upwardly secured to theuniversal rod 402%.

special stop wire.

printing mechanisms corresponding in general structure to the regularmechanisms may be provided at the left hand side of the adding machineproper.

. Describing the present embodimeint'of my invention as hereinillustrated, I provide a special stop wire 270 arranged to operate inthe uppermost or number 1 slots of the plates 210 corresponding with thecolumn of the counter section in which I wish to accumulate units, whichcolumn, in the present instance, corresponds wlth the second row of keysfrom the left hand side of the keyboard. It will be understood that thereguand the remaining to that denomination are unnecessary. This specialstop wire is placed under the control of some part of the regularmachine which is operated whenever an item is set up on the keyboard andfor this purpose I take advantage of the fact that the universal rod402% is operated or moved whenever an item is set up on the keyboard,whether the item contains one or more digits. To this end, the specialstop wireis made of the peculiar shape illustrated in perspective inFig. 5, in which such wire is shown as provided at its rearward end witha fork (1 adapted to fit over lar stop wire is removed the universal rod402-3 at a'point between the first and second denominations, countingfi'om the left of the keyboard, such rod being grooved, as shown in-Fig. *1, so as to hold such end of the special stop wire in properposition. This stop wire is bent at so as to form an upright portion 1)which is arranged to press against the forward edge of the retainer 415corresponding with the particular plates 210 with which the special stopwire cooperates. This special stop wire is also provided with aprojecting portion a forming a point of attachment for I end is .Thisspring forms a flexible connection between such rod and the special stopwire with the one end of a spring (1, whose other result that when theuniversal rod i. moved rearwardly in the manner already explained. saidspecial sto-p' wire is also moved rearwardly, thereby forming a stop forthe rack 610 in the number 1 slot. At the same time, by reason of thecontact of the portion 1) of the special stop wire against thecorrcsponding retainer 415. such retainer is rocked so as to release itsrack and permit descend until'stopped by such the same to The parts arethus set or put under such conditions that 1', may be accumulated whenthe machine is operated in the usual manner and will cause 1 tobe prmtedopposite each item according to the construction thus far d'escribedalthough as hereinafter explained, special mechanism is provided forpreventing the 1 from being thus printed when the items are beinglisted, but permitting only the total of the number of the items to beprinted in connection with and opposite the regular total printed by themachine. It willbe understood that the machine split between the secondand third denominations, counting from the left, as indicated in Fig. 3,so that the hammer action will not be transferred from the left handsection of the keyboard, which operating as the item counter, to theright hand section thereof, which is operating as a regular machine, andconsequently no ciphers will be printed in the right hand section to theleft of the item. The so-called split is effected by simply omitting thetail from the second latch to the right as clearly shown in Fig. 3.

'hen the operated keys are restored and the sliding bars 214 return totheir normal position, the universal rod 402?; is likewise restored toits normal forward position in the well known manner aiid as a resultthe sj'iecial stop wire is moved to its normal position illustrated inFig. 1, ready for the next operation .llowcver, in many cases, it isdesirable that the ls accumulatedby the special mechanism which iskeeping count of the number of checks or items should not he printed andto that end I provide mechanism which normally prevents action of theprinting mechanism corresponding to said two denominations whichare'here utilized for the special purpose of counting or accumulatingthe number of items.' In the present instance, an interference, underthe control. of the totalizing mechanism, is provided for interferingwith the action of the hammers corresponding tov such special mechanism,with the rsult that those 'hammers are prevented from delivering theirblows during the accumulatingand listing of items. but are permitted tooperate and deliver their blows in the ordinary manner and thereby causethe special total to be printed whenever the totalizing mechanism ofthejmachine is set and the machine operated for the taking of a total.This interference comprises a bail A shown more particularly in Figs. 2and 3 and secured at-its ends to a rock shaft A which is operativelyconnected with the totalizing mechanism through the link B, whoserearward end is pivotally connected with the crank arm B secured tosaidrock shaft. A and whose forward end is operatively connected to the samestud 251-} which forms the pivotal connection between the bell crank22-7 and. the link 226 of the regular Burroughsmachine. This bail isnormally held in a position of interference with a yieldingpressure, as

by means of the coiled spring e connected to the crank arm B -Moreover,in order that the bail may be caused to interfere only with the specialhammers marked 715* without interfering. with'the action 0ftheregu larhammers 715 at any time, such regular hammers are cut back at 715",while the special hammers are left of the usual construction. The resultof this arrangement isbetween said interference and the totalizingmechanism of the machine, the bail is rocked or swung upwardly to aninoperative position, as illustrated in dotted lines in Fig. 2, it beingunderstood that when the total key 265 is depressed and-the bell crank227 rocked in a clockwise direction, the link B is reciprocatedre'arwar'dly and the shaft A rocked in an anti-clockwise direction,there-' by elevating the bail A to an inoperative position, that is aposition to clear the' shoulders on the special hammers. When t-hetotalkey is thus set-or depressed for the taking ofa total, either sub-totalor grand total, the special hammers are permitted to operate in the samemanner as the regular hammers and the special total or accumulation isprinted atone side of the regular total and in an automaticmanner and asan incident to the taking of such regular total.
